Singing Nightmare

a haunting echo, a terrifying howl, that is what marks the presence of the Hydra assassin known as the Singing Nightmare. no one has ever seen this mysterious assassin who strikes from the shadows after freezing their target in absolute fear. they've never failed a mission and everyone whispers their name in fear. not because of their terrifying accuracy but because of their voice. before they attack from the shadows, they sing. not a nice lovely song, but a song that they somewhat howl and somewhat whistle making it echo against their surroundings. their voice is like something straight out of a nightmare and anyone who hears it freezes in fear unable to move. the only person who survived an attack of the Singing Nightmare was Bucky when he was the Winter Soldier because the Winter Soldier felt no fear and had no emotions. after the fall of Hydra people thought that the Singing Nightmare had died or just disappeared but they didn't. but what will happen when the Thunderbolts learn of the rise of the Singing Nightmare? you can be whoever you want. all the Thunderbolts are in this (if you've ever seen the singing in the stairwell videos by Lauren Paley then that's what the Singing Nightmare does)
